Actor fattens up as health foods prove unhealthy

An Australian actor who set out to expose hidden sugar in health foods said he gained 8.5 kilograms and a paunch after going on a 60-day low-fat diet that included yogurt, cereal, muesli bars and juices.

Damon Gameau's documentary, That Sugar Film, studies the effect of consuming what it says is the average daily sugar intake for Australian adults - the equivalent of 40 teaspoons - on the human body.

"I think you can't not be shocked by learning the average Australian consumes 40 spoonfuls of sugar per day, " Gameau said.
